Job stress and Disease History in Shift Work and non- shift Work Agencies Drivers of Yazd City

Introduction: One of the major problems in industrialized societies is occupational stress. This problem is associated with an increase in various diseases and drivers have a lot of exposure to this factor. According to the harmful effects of stress and drivers exposure with this agent, the aim of study was to review relationship of job stress and disease history of shift and non- shift work agency drivers of urban Yazd city. Methods: This research is a case - control study that is done in agency drivers of Yazd city. For this purpose, 142 shiftwork drivers and 125 non-shiftwork with random-quota sampling method were selected. In order to collect of research data was used from a two-part questionnaire. The first part is demographic and the second part is measuring job stress with Philip L. Rice questionnaire. Finally, the results were analyzed by spss software. Results: Analyses of the data showed that mean stress score of shift workers is higher than non-shift workers. In addition, the mean stress score based on the type of disease was showed that apart from the lack of sleep, in other diseases, there was no statistically significant difference. However, drivers with disease history had the higher mean stress score. Conclusion: High stress levels of drivers indicate the need to implement a comprehensive program of stress management in organizations. Therefore, should be further studies in this field

Prevalence of Job Stress among Staff of the Ports and Sailing Corporation of Hormozgan and its Relation to Non Fatal Accidents

Introduction: Investigation of job stress among people who have experienced accidents could help to recognize causes of events in workplaces. The objective of this study was to measure frequency and severities of work stressors among staff employed at the Hormozgan Ports & Sailing Organization, and determine its relationship with accidents. Methods: This cross-sectional study included 320 Hormozgan Ports & Sailing Organization staff that completed 3 questionnaires including demographic characteristics, stress frequency and stress reaction. Statistical analysis was performed by One way ANOVA and Chi square test. Results: The averages scores from frequency and reaction stressor questionnaires for all of the study population were 88.9 and 16.1 respectively.

The Odds Ratio of people with positive history of accidents in stress frequency questionnaire was 6.48. Conclusion: As seen in the results of this study, stress plays a role in non fatal accidents and therefore, quality management for the control of stress in workplaces is a necessity

Survey of noise exposure and permanent hearing loss among Shadris spinning factory workers of Yazd using Task Base Method (TBM)

Background and aims  During last decades one of the hazardous agents on workers health has been workplaces noise. The aim of this study was to investigate the level of noise exposure in different jobs and noise induced permanent threshold shift in relation to noise level and work experience.   Methods  This is a cross-sectional and descriptive study that performed among total workers. Dosimetry was done for determination of accurate noise exposure level during an eight-hour s shift for each job group. Audiometry was performed in a standard acoustic room by the audiologist. The obtained data was analyzed by means of SPSS software.   Results  Mean of age was 36.58 ± 6.76(19-52 years) and minimum, maximum and mean of work experience were 1 , 18 , 11.08 ± 5.47 respectively. Mean of hearing loss was 15.38 ±8.63 in right ear and 16.31 ±9.51 in left ear and total hearing loss was 14.72 ±8.33. A significant relationship was also identified between noise intensity and work experience with hearing loss (Pvalue?).   Conclusion  Findings of this study indicated that there is a high prevalence of noise pollution in different parts of workplace. Considering the obtained results, that shows positive effect  of noise and work experience on hearing loss,  the necessity of  improvement of control  and protection measures is of prime importance
